The concept of a floating island has been with us throughout history, but sprang back into the limelight just four years ago when Wally Yachts came up with an island-themed megayacht named the Wally Island.

This amazing-looking craft can’t quite work out whether it’s a boat or an island.

The Osros floating Island was designed to offer the billionaire superyacht lifestyle for mere millionaire money. It boasts six luxury double bedrooms, with space for 12 residents and accommodation for up to four staff members, all for a cool £3million.

There is what the manufacturers describe as an ‘autonomous power supply based energy system’ powered, both day and night, by a noiseless wind energy system, as well as more than 120 m2 of solar panels making the most use of daylight. Heat recovery from sea water is the basis for heating and air conditioning.

Buyers can tailor the interior and design to their individual needs. The sun deck area features sun roof loungers, a BBQ area, Jacuzzi, and a bar with seating for up to 15 people.

There is storage for water sports and diving equipment and a mooring for motor boats along with a handy hatch for loading and unloading of provisions.

The main deck hosts a spacious living room and lounge with exotic aquarium, regulated lighting and air supply.

The Wally Island was a 99 meter (325 feet) “gigayacht” design that dwarfed the vast majority of luxury megayachts and reconceived the yacht as a floating personal island, a mobile address that can be used as a home, an entertaining space or even a moving exhibition or show space.
